TEXT: Differential Equations and Linear Algebra, 2nd Edition, by Jerry Farlow, James E. Hall, Jean Marie McDill, Beverly H. West; Prentice Hall publisher.

PREREQUISITES: Within the last year, you must have completed a second semester or third quarter Calculus course with a grade of C or better. Concurrent enrollment in Math 2210 and Math 2250 requires departmental approval.

COURSE DESCRIPTION: To develop foundations for a theoretical understanding and working knowledge of ordinary differential equations and linear algebra as they relate to modeling problems in science and engineering.

COURSE OBJECTIVES: We develop standard classical techniques of solving ordinary differential equations including first order equations, second and higher order linear equations, systems, and Laplace transforms. We also examine the qualitative nature of solutions and study numerical methods to obtain solutions. Applications include population models, motion and resonance, equilibrium solutions, and electric circuits. The linear algebra portion includes the study of systems which may have none, one, or infinitely many solutions; vectors, determinants, matrices, and eigenvalues as they relate to solving systems of linear equations and systems of differential equations.

CALCULATORS: Graphing calculators and computer algebra systems are useful tools for demonstrating concepts and facilitating problem solving. They are not a substitute for learning the fundamental concepts of this course. Some homework assignments and projects may require the use of a graphing calculator or computer algebra software such as Matlab, or Excel.

A basic scientific calculator with a simple numeric store and recall memory may be used on in-class tests, including the final exam. Graphing, programmable, or calculators capable of symbolic manipulation are prohibited on in-class tests, including the final exam. Prohibited calculators include the TI-36X, TI89, TI92, TI-Nspire, HP 48SX, HP 48GX, as well as other models and brands. Computers, cell phones, and other communication devices are also prohibited on all in-class tests, including the final exam.

Also, a cell phone may not be used as a calculator on any in class exam or quiz.

CLASS SCHEDULE: Attached is a tentative schedule for the course. This schedule will be followed as closely as possible; however, some modifications may be necessary during the semester. Your instructor will announce all modifications in class.

Homework: Homework is due at the beginning of each exam. I encourage you to spend that evening before an exam reviewing rather than doing homework. Once again, please have your homework done before the review day so you can ask any questions.

NO LATE WORK WILL BE ACCEPTED FOR ANY REASON!

Examples done in class and homework problems are similar to the problems that will be on course examinations and the final exam. Regular practice is essential for success in mathematics. You should not only understand how to do the homework but why problems and theorems work the way they do. Learn the why’s of your homework, not just the how’s!

Computer Labs: There may be computer labs assigned as homework. All relevant software is accessible in the Math Dept. Lab (and may be available in other labs as well).

Exams: There will be four exams and a final exam during the semester. Exams will be taken during a scheduled class period. NO MAKE-UP EXAMS will be given. If you know you will be gone for an exam, please come and see me before the exam. If you email me concerning a scheduled exam that you need to miss, do not just assume that I received your email. You must speak to me in person. It is up to the discretion of the instructor to allow an exam to be taken at a different time and place. I only allow this once (if at all) and only if you have a valid reason supported with documentation. I waive the right to allow this if I think your reason is not valid. Full credit will be awarded on exam problems only if your work can be readily followed and work supported solutions are precise and clearly indicated. NO WORK, NO CREDIT!

Final Exam: The Finals schedule is found in the Spring 2015 Class Schedule. The location will be announced. It is NOT an option for the students to not take this exam. Students should make arrangements with employers now to be free at the appointed time. The final exam will be a comprehensive examination emphasizing topics listed under the course objectives. It is an SLCC Math Department policy that students attaining a score of less than 60% on the final shall receive a grade no higher than "D" for the course.

Permanent Folder: In case of human or computer error, keep all homework, projects, quizzes, and exams in a folder until you have received a grade for the course.

Cheating: The minimum penalty for students found cheating on an exam will be a “0” for that exam and possibly result in an “E” for the entire course. The student code of conduct covers this particular issue on pages 39-41. The link is: .

Classroom Deportment: Each student is responsible for his/her own behavior. Any student who shows a pattern of disrespect for others, or who at any time displays egregious disrespect for others, will be subject to penalties as per the student code of conduct. No cell phones may be used during class. Laptops may be used upon request.

Withdraw Policy: Students may withdraw from the course through Feb 24, 2015. Withdrawals will not be approved after that time

A 100 - 93% of possible points C 76 - 73%

A- 92 - 90% C- 72 - 70%

B+ 89 - 87% D+ 69 - 67%

B 86 - 83% D 66 - 63%

B- 82 - 80% D- 62 - 60%

C+ 79 - 77% E below 60%

The following is a breakdown of weights used in the calculation of the course grade:

WEIGHTS:

Homework/Projects/Flow Chart/Quizzes 30% of final grade

Chapter Exams 45% of final grade

Final Exam 25% of final grade

ATTENDANCE: Class attendance is STRONGLY advised. Regular attendance is essential to achieve satisfactory results. It is the student's responsibility to be aware of all material covered, tests dates, and assignment due dates. Your instructor will outline specific attendance policies.

ACCOMMODATIONS: Students with medical, psychological, learning or other disabilities desiring accommodations or services under ADA, should contact the Disability Resource Center (DRC).  The DRC determines eligibility for and authorizes the provision of these accommodations and services for the college.   Please contact the DRC at the Student Center, Suite 244, Redwood Campus, 4600 So. Redwood Rd, 84123.  Phone: (801) 957-4659, TTY:  957-4646, Fax:  957- 4947 or by drc@slcc.edu.

EXTRA HELP: Please use your instructor’s office hours to ask any questions - you can either phone or visit in person. You are also encouraged to send any questions via e-mail. Tutoring is available in the Math Lab (phone 957-4839) at Redwood SI092 or at the SCC Learning Center, N308. Finally, use each other as a resource! Study groups are invaluable and the Learning Center provides a convenient gathering place. A list of private tutors who may be hired is available in the Learning Centers.

RESOURCES FOR STUDENT SUCCESS: Please visit our CANVAS page. It contains very useful information, web links and, Matlab templates and reading for 2250. Caution: not all of the information will be used in your course.

STUDENT LEARNING OUTCOMES: SLCC is committed to fostering and assessing the following student learning outcomes in its programs and courses:

* Acquiring substantive knowledge in the field of their choice

* Developing quantitative literacy

* Developing the knowledge and skills to be civically engaged

* Thinking critically

* Communicating effectively

Finally, read and be aware of the regulations set forth in the Fall 2015 Schedule and the SLCC college catalog. Please see your instructor ASAP about any problems that are affecting your work in this class.
